IVIAN'UALv CONTROL FOR TURBINES.

YApplie'anorn filed August 1, 191s. seriai No. 247,853.

T o all whom t may concern.

Be it known that I, EARL H. SHERBONDY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Manual Controls for Turbines, of which the following is a specification. f

This inventionrelates'to means for controlling a turbine.

The turbine in question is designedto be v bushings 13, which are mounted in a control operated by the exhaust gases from an internal combustion engine and may be used to operate a centrifugalblower wheelto supply .air under pressure for combustion in the engine.

In my co-pending case Serial No. 234,557 filed May 14, y1918 I have'shown and claimed automatic means to control they speed of the turbine, so that it will'speed up and pump more air at higher altitudes. This auto-V matic control however, is somewhat compl1 cated and presents some liability to get out oforder. v v

It is an vobject of this invention to provide a manual control means *fory the turbine, which is simple in design and which presents ver little possibility of getting out of order. ther objects and advantages will appear as the description proceeds.

In the drawings, Figure'l is a side view of a turbine and control housing, partly in section; Figure 2'is a section on an enlarged scale on the line 2 2 of Figure 1; Figure 3 shows the manual control means and Figure 4 shows a modification.

Figure 1, indicates a turbinewheel mount.-

ed on the shaft 3 and provided with the usual buckets 2. Associated with the turbine, is a main casing element4, annular in' shape, being substantially shaped like a shallow dishpan. Associated with this casing is a backplate 5, which is attached at its outer edge to the casing 4.

Arranged within the casing 4, is an annu` f lar diaphragm 6, which defines an inlet chamber 7 and an exhaust chamber 8.

The fluid that is to operate the turbine is led thru suitable ports, (not shown in casing 4), in to the inlet chamber 7.

After passing thru the turbine buckets, it passes into the chamber 8, from whence it escapes to the atmosphere, thru one or more exhaust pipes 9.

The diaphragm 6, is provided with one or more apertures in which are mounted one or the turbine may be. controlled by moving the valves 11'. I

Thestems 12 of the valves 11, move in housing 14.v The other endsA of the valve stems 12,v are provided with Vdiscs 15. Ar',-

ranged between the discs 15 and arbearing disc 16, is a spring 17, which tends to hold the valve 1l in its closed position and so tends to counteract lthe pressure of the eX- haust gases 'supplied to the turbine against the right hand s ide of the valve 11.

yBearing against the discs 15 are cams 18 *ofthe shape shown, mounted on a cam shaft 19. It will be apparent that when the camshaft is rotated in the direction of the arrow in Figure 2, thatl the valves 11, will be opened, an amount proportional to the amount of rotation givento the camshaft.

- The camshaft 19 issuitably mounted as shown in the control `housing 14. This camshaft is intended to be rotated manually by any 'desired means. To this end it mayy 'be provided with a handle 20, which if convenient may be operated directly by hand, or it may be manually controlled from a distance, in any suitable way, such as by cranks and levers oras shownv by a Bowden wire 21, controlled by a handle 22, which may be locked vin any desired position on the segment 23.`

Referring now to Figure 4, anoil control means for the valve stems 12 is shown. A

control housing indicated generally at 24, 'carr1es-walls, defining an oil pressure that is rigidly -conneotedto the valve stem 12.

A. spring 17 serves the same purpose as in Figure 1. One side of the piston 28 is in connection with the oil pressure passage 25, so `that variation of this oil' pressure'will ycause movement of the piston, against the movement of the'spring 17.*v This oil pressureI may be varied bya balanced valve 29, which moves in a cylinder 30, 'mounted in-a suitable recess in the control housing 24.

In the position shown in Figure t, the oil passage 3l is closed with a valve 29 and ther oil in the pressure passage 25, is at a high pressure, and the valves 11 are open.

As the valve 29 is moved upwardly, it gradually opens the passage 3l to relieve the oil pressure therein and allow the springs 17 to close the-valves l1 and so speed up the turbine. The oil is drained from the inside of the cylinder 30, into the oil drain passage 26, thru a hole 32.

The valve 29 is held in its lower position, by spring 83, which is connected to the stein 34 of the valve 29, being held in position, by a cap 35, carried by a housing 24. The valve stem 34:', has connected thereto a rod or wire 36, with which it may be moved manually. This manual movement may be effected in any desired way, for instance, it may be controlled by a Bowden wire 21, which is manually controlled, as shown in Figure 3.

It should be understood that my invention maybe carried out in a number of other ways, than as illustrated, as defined within the scope of the following claims.

l. In combination with an exhaust chamber of a gas engine7 an annular inlet chamber having a constricted outlet 'tor a gas driven turbine, a vgas driven turbine near said outlet, a turbine exhaust chamber for r said turbine having a wall contiguous to said annular inlet chamber, and a by-pass for the hot gases 'from said inlet chamber to the turbine exhaust chamber through said contiguous wall, avalve for saidby-pass mounted in said turbine exhaust chamber, resilient means normally tending to-seat ysaid valve, vthe stein of said valve extending through the non-contiguous wall of said turbine exhaust chamber, a disk iixedly secured to the extended portion of said valve stein, and manually controlled means operating said disk to controlfthe position of said valve.

2. In combination with the casing of a gas turbine, a partition dividing said casing substantially into an inlet chamber for the -exliaust gases of a gas engine, with a con- `striction at one end, and a Haring exhaust chamber for a gas turbine, a gas turbine with its periphery substantially in line with said partition at its constricting end, a by pass in said partition, a valve for said bypass, resilient means normally tending to seat said valve, valve supporting means for said valved by-pass in said flaring exhaust chamber, the stem of said valve extending through the non-contiguous wall of said turbine exhaust chamber, a'disk fixedly secured to the extended portion of said valve stem,
